Hi Davidp158,
I was just checking the download and its content, while you have found it already. Let me add the screen shot here, if someone runs into the same problem.
I check the content on a MacBookPro from 2010, which should allow to show if something overwhelms the “engine”. I personally couldn’t find a problem.
Perhaps a sign that something needs to be discussed with the support? http://www.maxon.net/support/support-questions.html
I have checked if I have an option to ping him a PM or e-mail via Cineversity, but no option on my side. I hope the QA team will have an answer for you soon.
However, let me say that I know that feeling when you have managed to make some time for tutorials and then it’s not working: sorry for that.
If you need to set up some cogwheels for a project right now, open a thread in the “Q&A-Forum” here and I’m happy to share my ideas to support your target.
My best wishes
